Some Cubans might not agree with this portrayal of Cuba at this time. Paterson covered all of her bases when it comes to researching the basic story, and Lora isn't at all condescending to her students. This is selectively representative of the climate at the time, and focuses on the positives of Castro's early days, glossing over the bad things that occurred.
I wish the cover incorporated some of the period photographs of brigadistas, so it would be very clear that this was a historical novel. There are some resources online, and I can see this book being a great starting point to an exploration of Cuban history. Even if this were an #ownvoices book, I can see there being a lot of different opinions about this reading program, no matter how positive it is in concept. Young readers need to understand that stories are often complex.
